Setting user groups

Hi.........

I'm trying to set a group of users to login to do a required super-user tasks without knowing the super-user passwd.

For example...a user popodude logs in as self with passwd..system accepts the password & then automatically asks for the super-user account passwd.

My goal is for the system to take this user directly to the task without asking for the super-user passwd.
Thanks,
Remi
